Photosynthesis Part 2 PRELAB Individual Assignment (10pts) Name: Perla N. Garcia Date: 10/10/23 Instructor: Yiting Xu Section Number: Instructions : Using the UTA library databases, find one primary literature source that is pertinent to your group’s photosynthesis experiment. The primary source you locate should be scientific research that would provide background information on photosynthesis, the variable you are testing, characteristics of the plant you are testing, or anything else you think would be important to know in order to understand your experiment. Upload this AND the article you selected to the submission link. Then, bring both the assignment AND a printed hard copy of your article to class next week. You will use these as part of your in-class activities for the day. Tip: Do not bring the same paper as your group members. The goal is to bring different papers that you will share with your group in a discussion. This should give you several solid resources for which to understand your experiment and write your lab report. For your source provide the following information : 1. Title of the article. - Pitch Perfect: Investigating the Effects of Different Wavelengths of Light on the Rate of Photosynthesis and Grass Growth 2. List all authors on the paper. - Richard Spencer 3. Name of the journal in which the article was published. - School science review 4. Volume, issue, and year. - School science review , 2018, Vol.100 5. Motive for the study. Why was the study conducted? - This study's main goal is to evaluate the best energy-efficient lighting options, with a focus on figuring out which light colors are most useful. Simply said, the goal is to identify the bulbs that are most effective in achieving the desired light hues.

6. Objective . What were the authors hoping to learn? - The researchers sought to discover which particular light can aid in the photosynthesis of the grass that grows in our daily life when exposed to sunlight. He examines the many wavelengths that each hue has to ascertain how it can imitate the wavelengths of the energy source used by the chloroplast in grass. 7. Outcome . What did the study conclude? - When exposed to various illumination conditions, comparing the color of chloroplast extracts in the experimental tubes with the color reference tube presented a challenge. However, a solution to this problem was offered by the employment of remote-controlled bulbs, which could be periodically converted to "white" light for color matching. The bulbs also had the added advantage of staying cool, which prevented temperature changes towards it. 8. Implication . What is the relevance of the author’s findings? What does the outcome of their study mean, why is it important? - This was crucial since fluctuations in temperature could negatively affect both the speed at which grass grows and the pace at which DCPIP loses its color. So, it was able to safely and continuously run the lamps for six days without any heat buildup, which supported the experiment's unhindered progression. 9. How does the information in the article relate to your A. vulgare experiment? - The topic that the article concentrates vaguely is largely on the type of wavelength in which the chloroplast can be affected to seeing how photosynthesis can be slowed, or sped up based on the wavelength of our selected colors. This study in the article considers its test subject for the grass growth while our experiment takes the idea of utilizing cabbage that has already been grown compared to the grass. It can be seen that this information over how each part has taken place will be able to give our own experience a more knowledgeable take once we reveal the results.
